BackgroundOccupational stress and its related psychological strain is a concern among resident doctors that may affect patient care adversely. Residents face many stresses because of their high job demands in delivery of hospital care. They are often subject to work load and pressure due to direct involvement with patients, prolonged working hours, poor job opportunities and low support. Their multiple educational and clinical roles can also affect their performance and quality of personal or professional life. The aim of this study was to evaluate the occupational stress among residents of various medical specialties.We aimed to explore the reasons of occupational stress in residents’ life and determine how we can enhance the stress-coping strategies and create more suitable conditions.MethodsThis cross-sectional analytical-descriptive study was conducted on all medical residents with various specialties in Shiraz University of Medical Sciences. Data was collected using Osipow occupational stress questionnaire and analyzed by SPSS software version 17.ResultsThe response rate was 88.8%. The average stress score of all residents was 156.35 out of 250. The highest and lowest average stress scores belonged to gynecology and dermatology specialties, respectively. The highest average score of the stress factors was related to the workload with the score of 35.09 of 50 (moderate to severe stress). The total stress score had a significant relationship with age (P = 0.030) and sex (P = 0.009) as well as lack of time to get the needed healthy meals (P = 0.047), high work hours (P < 0.01), surgical specialties (P < 0.01) and on call shift (P < 0.01).ConclusionSince most of the stressors were related to the workload, interventions such workload reduction, education about occupational stress and its management, promoting interpersonal relations and more supportive measures are recommended.

Aim:This study investigated the effect of one hemostatic agent on the shear bond strength of self-etch and etch-and-rinse adhesive systems.Materials and Methods:Sixty extracted third molars were selected. After preparing a flat surface of superficial dentin, they were randomly divided into six groups. Adhesives were Tetric N-Bond, AdheSE, and AdheSE One F. Before applying adhesives, surfaces were contaminated with ViscoStat for 60 s in three groups and rinsed. Then composite were attached to surfaces and light cured. After thermocycling, the bond strength was calculated and failure modes were determined by stereomicroscope. The data were analyzed by t-test and one-way ANOVA with P < 0.05 as the level of significance.Results:ViscoStat had significantly decreased the shear bond strength of AdheSE (P < 0.0001) to dentin. Modes of failures in all groups were mainly adhesive.Conclusion:Contamination had an adverse effect on the shear bond strength of AdheSE and reduced it.
